1.2 Alternative Distribution Theories: Ricardo, Kaldor, Kaleeki

I. Introduction to Alternative Distribution Theories

Overview of Distribution Theories

Definition and Importance
Distribution theories in economics are frameworks that explain how income and wealth are distributed among different factors of production, such as labor, capital, and land. These theories are crucial for understanding economic inequality, policy-making, and the dynamics of economic growth. They help in analyzing how different economic policies affect the distribution of income and wealth, thereby influencing social and economic stability.

Historical Context

Evolution of Distribution Theories
The study of income distribution has evolved significantly over time. In the early 19th century, classical economists like David Ricardo laid the foundation for distribution theories with his Principles of Political Economy and Taxation (1817). Ricardo’s work focused on the distribution of income between landowners, capitalists, and laborers. In the mid-20th century, Nicholas Kaldor introduced his alternative distribution theory, emphasizing the role of savings and investment in income distribution. Around the same time, Michal Kalecki developed his theory, which incorporated elements of monopoly power and class struggle into the analysis of income distribution.

Key Economists

Contributions of Ricardo, Kaldor, and Kalecki

• David Ricardo: Ricardo’s theory of distribution is centered on the labor theory of value, which posits that the value of a good is determined by the amount of labor required to produce it. He introduced the concept of economic rent, which is the income earned by landowners due to the scarcity of land. Ricardo’s theory also includes the subsistence wage theory, suggesting that wages tend to gravitate towards a subsistence level, and the profit theory, which highlights the role of capital accumulation in determining profits.
• Nicholas Kaldor: Kaldor’s distribution theory, presented in his seminal paper “Alternative Theories of Distribution” (1955), challenges the classical view by focusing on the relationship between savings, investment, and income distribution. He argued that the distribution of income between wages and profits is determined by the propensity to save out of profits and wages. Kaldor introduced the concept of marginal productivity theory, which explains how the distribution of income is influenced by the marginal productivity of labor and capital.
• Michal Kalecki: Kalecki’s theory of distribution incorporates elements of monopoly power and class struggle. He argued that the degree of monopoly, which refers to the market power of firms, plays a crucial role in determining the distribution of income. Kalecki also emphasized the importance of mark-up pricing, where firms set prices above marginal costs to earn profits. His theory highlights the conflict between labor and capital, with income distribution being influenced by the bargaining power of workers and capitalists.

Objectives

Analyzing, Comparing, and Criticizing Different Theories
The primary objective of studying alternative distribution theories is to analyze, compare, and criticize the contributions of Ricardo, Kaldor, and Kalecki. This involves:

• Analyzing: Understanding the fundamental principles and assumptions of each theory, and how they explain the distribution of income and wealth.
• Comparing: Identifying the similarities and differences between the theories, such as their views on the role of labor, capital, and land in income distribution.
• Criticizing: Evaluating the strengths and weaknesses of each theory, considering their empirical validity, relevance in contemporary economic contexts, and policy implications.

II. Ricardo’s Distribution Theory

Basic principles

Labor theory of value
David Ricardo’s labor theory of value posits that the value of a commodity is determined by the amount of labor required to produce it. This theory, elaborated in his book On the Principles of Political Economy and Taxation (1817), suggests that goods are exchanged based on the labor time embodied in them. Ricardo, along with Adam Smith and Karl Marx, argued that labor is the source of all value in an economy. For example, if it takes 20 hours to produce a pair of shoes and 10 hours to produce a hat, the shoes would be valued twice as much as the hat.

Subsistence wage theory
Ricardo’s subsistence wage theory, also known as the iron law of wages, asserts that wages naturally tend to gravitate towards a subsistence level. This means that workers’ wages will be just enough to sustain their lives and enable them to work. If wages rise above this level, the population would increase, leading to a surplus of labor and a subsequent drop in wages back to the subsistence level. Conversely, if wages fall below subsistence, the population would decrease, causing wages to rise again.

Rent theory

Differential and absolute rent
Ricardo’s rent theory distinguishes between differential rent and absolute rent.

• Differential rent: This arises due to differences in the fertility and productivity of land. Ricardo identified two types:
  • Differential Rent I: Extra profit is transformed into rent when equal amounts of capital are invested on lands of unequal productivity.
  • Differential Rent II: Differences in profitability result from unequal amounts of capital being invested successively on the same type of land.
• Absolute rent: This type of rent is extracted by landowners due to their monopoly over land. It arises because agricultural production has a lower organic composition of capital compared to industry, meaning that the value of agricultural output is higher than its production cost.

Profit theory

Role of capital accumulation
Ricardo’s profit theory emphasizes the importance of capital accumulation in determining profits. He argued that profits are what remain after wages and rents have been paid from the gross revenue. Capitalists invest in both fixed capital (like machinery) and working capital (like wages). According to Ricardo, the rate of profit is influenced by the productivity of labor and the cost of production. He also noted that as capital accumulates, the rate of profit tends to fall due to the diminishing returns on investment in agriculture.

III. Kaldor’s Distribution Theory

Basic principles

Marginal productivity theory
Nicholas Kaldor’s marginal productivity theory posits that the distribution of income between wages and profits is determined by the marginal productivity of labor and capital. This theory suggests that each factor of production is paid according to its contribution to the production process. Kaldor emphasized that the share of income going to labor and capital depends on their respective marginal products. For example, if the marginal product of labor increases due to higher productivity, wages would rise accordingly.

Role of capital and labor
Kaldor highlighted the interdependence between capital and labor in determining income distribution. He argued that the distribution of income is influenced by the relative shares of capital and labor in the production process. In his view, the accumulation of capital leads to higher productivity, which in turn affects the distribution of income. Kaldor’s approach integrates the dynamics of savings and investment, showing how these factors impact the overall economic growth and income distribution.

Savings and investment

Impact on income distribution
Kaldor’s theory underscores the crucial role of savings and investment in shaping income distribution. He argued that the propensity to save differs between capitalists and workers, with capitalists typically saving a larger proportion of their income. This differential saving behavior influences the distribution of income, as higher savings lead to increased investment and economic growth. Kaldor’s model suggests that shifts in income distribution are essential to achieving a higher saving-income ratio, which is necessary for sustained economic growth.

Technical progress
Influence on distribution
Kaldor introduced the concept of the technical progress function, which replaces the traditional production function. According to Kaldor, the rate of increase in output per worker is an increasing function of the rate of investment. This means that technical progress, driven by investment, plays a pivotal role in determining the distribution of income. Kaldor argued that technical progress acts as the main engine of growth, influencing productivity and, consequently, the distribution of income. For instance, advancements in technology can lead to higher productivity, thereby increasing the share of income going to labor.

IV. Kalecki’s Distribution Theory

Basic principles

Degree of monopoly
Michal Kalecki’s degree of monopoly theory introduces a unique approach to understanding income distribution. This theory suggests that the degree of monopoly power held by firms determines their ability to set prices above marginal costs. Kalecki argued that firms with higher monopoly power can charge higher mark-ups, leading to greater profits. This concept is crucial for analyzing how market structures influence income distribution. For example, in industries with few competitors, firms can exercise significant monopoly power, resulting in higher mark-ups and profits.

Mark-up pricing
Kalecki’s mark-up pricing theory explains how firms set prices by adding a mark-up to their prime costs, which include wages and raw materials. This mark-up covers overheads and ensures profitability. Kalecki emphasized that the size of the mark-up depends on the degree of monopoly power. Firms with greater market power can impose higher mark-ups, leading to higher prices and profits. This pricing strategy is prevalent in various industries, including manufacturing and services, where firms seek to maximize their returns by leveraging their market position.

Role of class struggle

Labor vs. capital
Kalecki’s theory incorporates the concept of class struggle between labor and capital. He argued that income distribution is influenced by the bargaining power of workers and capitalists. In this framework, wages and profits are determined by the relative strength of labor unions and employers. For instance, strong labor unions can negotiate higher wages, reducing the share of income going to capitalists. Conversely, weak labor unions result in lower wages and higher profits for capitalists. This dynamic reflects the ongoing conflict between labor and capital over the distribution of economic resources.

Savings and investment

Impact on income distribution
Kalecki’s theory also examines the role of savings and investment in income distribution. He argued that capitalists save a larger proportion of their income compared to workers. This higher savings rate leads to increased investment, which in turn affects income distribution. Kalecki suggested that the distribution of income between wages and profits is influenced by the level of investment in the economy. Higher investment levels can lead to greater economic growth, but they also reinforce the income disparity between capitalists and workers.

V. Comparative Analysis of Distribution Theories

Theoretical foundations

Assumptions and implications

• Ricardo: David Ricardo’s distribution theory is based on the labor theory of value, which assumes that the value of goods is determined by the labor required for their production. This theory implies that income distribution is influenced by the productivity of labor and the availability of land. Ricardo’s assumptions include the subsistence wage theory, which suggests that wages tend to stabilize at a subsistence level, and the concept of economic rent, which arises from the scarcity of land.
• Kaldor: Nicholas Kaldor’s distribution theory relies on the marginal productivity theory, which posits that income distribution is determined by the marginal productivity of labor and capital. Kaldor’s assumptions include the differential saving behavior of capitalists and workers, with capitalists saving a larger proportion of their income. This theory implies that income distribution is influenced by the propensity to save and invest, as well as the rate of technical progress.
• Kalecki: Michal Kalecki’s distribution theory is centered on the degree of monopoly, which suggests that firms with higher monopoly power can set prices above marginal costs, leading to greater profits. Kalecki’s assumptions include the role of class struggle between labor and capital, with income distribution being influenced by the bargaining power of workers and capitalists. This theory implies that market structures and the degree of monopoly power play a crucial role in determining income distribution.

Empirical evidence

Real-world applications and case studies

• Ricardo: Empirical evidence for Ricardo’s theory can be observed in historical and contemporary agricultural economies, where land scarcity leads to economic rent. For example, in India, the Green Revolution increased agricultural productivity, but the benefits were unevenly distributed, leading to higher rents for landowners.
• Kaldor: Kaldor’s theory finds empirical support in the analysis of savings and investment patterns in developed economies. For instance, in post-independence India, the government’s focus on industrialization and investment in infrastructure led to significant economic growth and changes in income distribution.
• Kalecki: Kalecki’s theory is supported by empirical studies on market structures and monopoly power. In India, the dominance of large conglomerates in sectors like telecommunications and pharmaceuticals illustrates how monopoly power can influence pricing and income distribution.

Policy implications

Recommendations for economic policy

• Ricardo: Ricardo’s theory suggests that policies should focus on improving labor productivity and managing land resources effectively. Land reforms and investments in agricultural technology can help address issues related to economic rent and income distribution.
• Kaldor: Kaldor’s theory implies that policies should encourage savings and investment, particularly in sectors that drive technical progress. Tax incentives for investment, support for research and development, and measures to increase the savings rate can help achieve a more equitable income distribution.
• Kalecki: Kalecki’s theory highlights the importance of regulating monopoly power and ensuring fair labor practices. Policies aimed at promoting competition, strengthening labor unions, and implementing progressive taxation can help mitigate the effects of monopoly power on income distribution.

VI. Criticisms and Modern Relevance

Criticisms of Ricardo

Relevance in contemporary economics

• Labor theory of value: Critics argue that Ricardo’s labor theory of value is overly simplistic and does not account for the complexities of modern economies. The theory assumes that labor is the sole source of value, ignoring other factors such as technology and capital.
• Subsistence wage theory: Ricardo’s subsistence wage theory is criticized for not considering the variations in living standards and wage negotiations in contemporary economies. The theory assumes that wages naturally gravitate towards a subsistence level, which is not always the case in modern labor markets.
• Economic rent: While Ricardo’s concept of economic rent is foundational, it does not fully explain the complexities of modern real estate markets and the role of government policies in land use and taxation.

Criticisms of Kaldor

Relevance in contemporary economics

• Marginal productivity theory: Kaldor’s marginal productivity theory has faced empirical challenges, particularly in explaining income distribution in economies with high levels of inequality. Critics argue that the theory does not adequately address the role of power dynamics and institutional factors in income distribution.
• Savings and investment: Kaldor’s assumption of invariable shares of income saved by capitalists and workers is considered too rigid. Empirical evidence shows that these shares tend to change over time, influenced by various economic and social factors.
• Technical progress: While Kaldor’s emphasis on technical progress is significant, his model does not fully account for the impact of technological advancements on employment and wage disparities in contemporary economies.

Criticisms of Kalecki

Relevance in contemporary economics

• Degree of monopoly: Kalecki’s focus on the degree of monopoly is criticized for oversimplifying the complexities of modern market structures. Critics argue that the theory does not fully address the role of government policies, international trade, and technological changes in shaping income distribution.
• Class struggle: Kalecki’s emphasis on class struggle between labor and capital is seen as too deterministic by some economists. The theory does not account for the nuances of labor market dynamics and the impact of globalization on labor relations.
• Savings and investment: Kalecki’s model does not fully explain the role of financial markets and global capital flows in influencing savings and investment patterns in contemporary economies.

Modern adaptations

How theories have evolved over time

• Ricardo: Modern adaptations of Ricardo’s theories have incorporated elements of neoclassical economics, focusing on the role of technology and capital in value determination. The concept of economic rent has been expanded to include various forms of rent-seeking behavior in different sectors.
• Kaldor: Kaldor’s theories have been integrated into post-Keynesian economics, emphasizing the role of demand-led growth and the importance of government intervention in managing economic cycles. His ideas on savings and investment have influenced modern growth models that consider the impact of financial markets and global capital flows.
• Kalecki: Kalecki’s theories have been adapted to analyze the impact of monopoly power and income inequality in contemporary economies. His ideas on class struggle have been expanded to include the effects of globalization and technological changes on labor markets.
